We developed a jelly infusion method enabling the evaluation of the duodenal ulcer. From February 1992 to April 1993, ultrasonic probe (USP) were performed in 100 lesions of duodenal ulcer (32 single anterior ulcers, 2 single posterior ulcers, 66 multiple ulcers) using this method. The following conclusions were obtained ; Detection rates of duodenal ulcers were 80% in anterior ulcers, 31% in posterior ulcers, 85% in single ulcers and 52% in multiple ulcers, respectivelly. Extraluminal ulcer echos of U1-IV duodenal ulcers were detected in 3/10 lesions (30%) at healing stage and in 32/36 lesions (11%) at scar stage using USP. Regarding the depth of duodenal ulcers diagnosed by USP the ulcers consist of 2% of U1-II, 30% of U1-III and 68% of U1-IV, respectivelly. Number of folds, central depression, surrounding protrusion and deformity in endoscopic findings at S1 stage reflected the depth of ulcer evaluated by USP. The accumulative healing rate of U1-III ulcers was better than that of U1-IV for all term. Thus, we conclude that USP with the jelly infusion method was useful in follow-up of duodenal ulcer.
